Had A.C. installed in 2016, after only 3 years the coil developed a leak. A new Unit was installed in 2019, the unit after only 2 years has developed a coil leak. Was charged $200.00 for initial service call and $600.00 to have new unit installed. Was just billed $300.00 for new service call. $1,100.00 for service and replacement of defective equipment that only lasts 3 years at the most is unacceptable. User's recommendation: Do not purchase a Trane A.C.
